What do Dhani Harrison, Jethro Cave, Amber Le Bon, and Tara and Merlin Ferry have in common? Is it that their fathers’ names feature among the titans of 20th-century rock and pop? Is it that — with apologies to the anti-nepotism police — they’ve inherited the family looks and talent? Or is it simply that they like a decent whistle and flute? Perhaps all of the above. On November 3, Antony Price — the man who dressed Bryan Ferry when he was in Roxy Music and who was the sartorial brains behind Duran Duran’s seminal video for Rio — launches a line of suits for Topman. And the next generation of rock-star kids are giving it their seal of approval.

DHANI HARRISON

While some of the other Beatles kids lead high-profile lives, Dhani — 30-year-old musician, self-described techno-geek and only son of the late George Harrison — is almost obsessively keen to stay out of the spotlight. He prefers to spend his time at home in Venice Beach, California, where he has a house code-named Stonyfield Farm, an imaginary commune where his friends can get together to play music and talk about ideas. For the release of the debut album of his band, thenewno2, Dhani will not be hauling himself around the chat-show circuit. Instead, he will release his slice of post-apocalyptic rock — Radiohead meets the Beach Boys with some Jimi Hendrix thrown in — on iTunes and a “memory chip”. He’s into all that techie stuff: he read industrial design at university, trained at McLaren Formula One, is on the board of a technology company and consults for Rockstar video games. “Yeah, I’m a nerd,” he says. “I want to know what’s next.” His modesty extends to his fanbase: his weekly residency at Key Club in LA has been attracting 1,000-strong crowds — Kate Bosworth, Zooey Deschanel and Princess Eugenie among them — but he doesn’t tell me that, someone else does. When I ask the man who must have met every music icon of the past 30 years who has impressed him the most, he shrugs. “Above all, someone with manners who knows how to be themselves,“ he says. “Take RZA from Wu-Tang Clan. He is nerdy enough to name his weird gang members after Chinese films, and look what they became.” And the suit? “It’s Dior Homme, but I’d really like someone to make a nice one just for me. I’m in love with civilised living and dressing, but I’m super-skinny, so suits never fit me. But it’s whatever serves me best. My girlfriend helps out.“

JETHRO CAVE AND AMBER LE BON

What does Amber Le Bon, 19, daughter of Simon, think about male dandies? “I don’t mind what boys wear, as long as they’re taller than me — and smell nice,” she says. No mention there of antipodeans, but on both other counts, Jethro, Nick Cave’s 17-year-old son from a previous relationship — 6ft 2in, nary an inch wide and smelling reasonably fresh — fits the bill perfectly. Jethro arrived from Australia the day before this shoot, leaving Melbourne because, he says with a chuckle, “things got a little bit hectic”. The plan is to “relax” for a while, stay with friends in east London, who may or may not return soon from a jaunt to Vegas, and probably do some modelling. He’s a proper peacock, this one — he gets his suits from charity shops (“I just buy ’em and wear ’em”) and doesn’t mind spending a few hours on a look. Today’s get-up — before being replaced with a Topman suit for these pictures — consisted of a beat-up leather jacket (bought in Brighton, where his dad lives with his wife, Susie Bick, and their two sons), skinny jeans, boots repaired with gaffer tape, a bum bag featuring an Aussie flag and a self-administered undercut. At a recent festival in Oz, his alter ego was “Joffle, king of the troglodytes”, resplendent in a cloak and with a staff. The urge to wear a dress can also be strong. “Well, you’ve got to frock up sometimes,” he says. Which reminds me of something Amber said: “Their heels can’t be higher than mine.” We know what Jethro would say to that.

MERLIN AND TARA FERRY

Does being the progeny of England’s most debonair rock star confer an instinctive sense of what’s stylish and what’s not? In the case of Merlin (left) and Tara Ferry — sons of Bryan, younger brothers of Otis and Isaac — the answer is probably yes. Obviously, the first rule is to not admit it. “I don’t think about what I’m going to wear,” says Merlin, who is 17 and doing A levels at Marlborough College. “If you take more than half an hour to get ready, you’ve got a problem with yourself.” Then it turns out he walks around school in a Comme des Garçons suit with, possibly, a Comme des Garçons shirt underneath (“Yeah, I’ve got a white one, I think”), and it’s no longer a question of whether this man knows what he’s doing. His brother, Tara, 19, who has a band, Rubber Kiss Goodbye, and is about to start a foundation course at Chelsea College of Art and Design, is slightly more forthcoming. “I do care about clothes. My wardrobe is pretty organised: white suits, leather jackets, different smart jackets. I avoid tracksuits and hoodies, anything naff like that.” Does Ferry Snr’s famous wardrobe come into the picture? “He’s got a lot of jackets and hundreds of pairs of shoes. He’ll say, ‘Oh, try this on.’ And I will — and steal it.” And what of women? What secrets has England’s most notorious lady magnet passed down to his third- and fourth-born? “What women want? It’s an unknown answer,” sighs Tara. “You can never know for sure.”
